Abstract:

This is the final report on a project funded for 3 years by ONR. The project was very successful it resulted in the discovery of many new solid state ternary nitrides. Since there were so few ternary nitrides known, and since many of the binary nitrides, such as TiN, AlN and Si3N4, are so technologically useful, our aim was to explore the synthesis, structural chemistry and properties of ternary nitrides. Prior to our work very few ternary nitrides, other than those formed by alloying binaries and having simple binary like structures, were known. We have shown that there is indeed a very large class of such ternary nitrides.
